When trying to login to the TDM Portal, I am receiving the following error message: License is not valid. Please activate/renew your license.
This error message means that either you have not applied your license in Datamaker yet or your TDM license is expired.
Once you apply the license in Datamaker, the Portal will pick up on the license and you should be able to login.
This document outlines how to obtain and apply a new TDM license: https://www.ca.com/us/services-support/ca-support/ca-support-online/knowledge-base-articles.TEC1469466.html
